Unnamed armed forces personnel
Air Force
Omaha Base captain
A USAF captain was on duty supervising the RADAR technician, Webb, when the USS Enterprise was detected over Earth in 1969. The captain telephoned Air Defense Command to report the sighting of the starship, referring to it as a UFO. (TOS: "Tomorrow is Yesterday")
Air force guard
This Air force guard watched over Colonel Fellini's office, while he was interrogating Kirk. He greeted Major John Christopher when he approached the door, before Christopher knocked him unconscious. He holds the rank of Airmen Basic, the lowest rank in the Air Force. (TOS: "Tomorrow is Yesterday")
Air policeman
The Air policeman accompanied Colonel Fellini when Kirk and Sulu inadvertently triggered a silent alarm while retrieving tapes so that there would be no record of the Enterprise traveling back in time. Spock rescued Kirk by overpowering Fellini and the policeman. He holds the rank of Airmen Basic, the lowest rank in the Air Force. (TOS: "Tomorrow is Yesterday")
Air police staff sergeant
The Air police staff sergeant was a non-commissioned officer stationed at the 498th Air Base in Omaha, Nebraska in 1968. His job was to enforce laws and regulations on an air force base, and to supervise other enlisted men performing the same tasks.
An accident catapulted the USS Enterprise back to the year 1969. Matters were further complicated when it destroyed an interceptor aircraft, and brought the pilot aboard. Forced to return him to avoid damage to the timeline, Kirk and Sulu sought a way to make his report less credible. To do this, they beamed into his base to retrieve the hard evidence of their presence. While they were retrieving the audio recordings, they were surprised by an air police sergeant, who took their equipment, inadvertently activating the emergency signal. Spock immediately beamed the source of the beacon – the sergeant – to the Enterprise, further endangering the timeline and complicating the mission. Aboard ship, the sergeant was clearly overwhelmed by what he saw around him, and never left the transporter room. A helpful Kyle even served him chicken soup there.
The sergeant was returned to his proper time and place during the slingshot effect experiment that returned the Enterprise to its proper time and place, effectively erasing the history in which he visited the ship. (TOS: "Tomorrow is Yesterday")
